The data of 48 field experiments conducted during 1999 to 2003 under on-station conditions for assessing the tillage requirements of 5 cereals (rice, wheat, maize, pearl millet and finger millet), 2 oilseeds (groundnut and soyabean) and one pulse crop (cluster bean) under different soil and climatic conditions at 13 centres of All India Coordinated Research Project for Dryland Agriculture are presented. Based on the data generated from field experiments with conventional tillage, low tillage + hand weeding and low tillage + herbicide application, a detailed statistical assessment of superiority of tillage practices was conducted. Results indicated that conventional tillage was superior at Bangalore, Karnataka for finger millet under semiarid Alfisols; peal millet under semiarid Vertisols of Solapur, Maharashtra and arid Inceptisols of Agra, Uttar Pradesh; rice under moist subhumid Oxisols of Phulbani, Orissa and dry subhumid Inceptisols of Varanasi, Uttar Pradesh; maize under dry subhumid Inceptisols of Rakh Dhiansar, Jammu and Kashmir; wheat under moist subhumid Inceptisols of Ballowal Saunkhri, Punjab; and soyabean under semiarid Vertisols of Indore, Madhya Pradesh. Low tillage + herbicide application was found to be superior for rice under humid Oxisols of Ranchi, Jharkhand; maize under dry subhumid Inceptisols of Ballowal Saunkhri; soyabean under moist subhumid Vertisols of Rewa; and cluster bean under semiarid Aridisols of Dantiwada. LOw tillage + hand weeding was found to be superior for pearl millet under semiarid Aridisols of Hisar, Haryana and groundnut under semiarid Alfisols of Anantapur, Andhra Pradesh.
